Translate text, detect a language, or list supported languages against any LibreTranslate-compatible instance.

You need to bring an instance or a key. For translation that works with no key of your own, use deepl — deepl_translate covers the same languages and Pipeworx fronts the key.

Tools

Auth

Bring your own, one of:

• _apiKey — an API key from https://portal.libretranslate.com (libretranslate.com is now key-only)
• _endpoint — the base URL of a self-hosted instance (https://github.com/LibreTranslate/LibreTranslate)

Given neither, every tool returns {found: false, reason: "requires_key_or_endpoint"} with a pointer to deepl_translate. It does not attempt the call.

Why it is gated

This pack used to hardcode libretranslate.com and call it with no key. That endpoint moved behind an API key, so every call returned the upstream’s raw 400 — “Visit portal.libretranslate.com to get an API key” — which reads to a caller as Pipeworx being broken rather than as a source needing a key.

The obvious fallback was a free public mirror. There aren’t any left. Checked 2026-08-06:

So the pack is honestly BYO rather than quietly broken. It is registered in the gateway’s BYO_ONLY_KEY_PACKS, which sinks it below deepl_translate in routing and labels it, so an agent asking to translate something reaches the tool that can answer.
